Job listings with filters React + Tailwind

Hello, I would like to ask for help about those two things:

1. When one or two job offers are filtered, my footer does not stick to the bottom of the page. How to fix this?
2. I have difficulties with responsiveness on screens lower than 350px, especially when the div with filtered buttons is open. My logo and the mentioned div are covering each other.

I would really appreciate your help and any other feedback.
